I'm losing too much hair ㅜㅜ

Last year, I suddenly experienced excessive hair loss, so I tried changing shampoos and consistently massaged my scalp, and it improved.

However... recently, after washing my hair, I notice a lot of hair falling out. Could this be a seasonal temporary hair loss? I have received treatment at a Korean medicine clinic.

It temporarily improves only when received, but once the management stops, it returns to the original state. I'm curious how people who manage their hair loss at home do their care.
